• 巯基

  After end-capped the remaining carboxylic groups of single-walled carbon nanotubes by covalent sulphydryl groups, the last electrode was applied to detect arsenic(III) and a limit of detection (LOD) (S/N = 3) of 0.008μg L-1 was obtained.

  利用巯基乙醇以共价键合方式对单壁碳纳米管的羧基进行封尾后,所得到的修饰电极被用于As(III)的痕量检测,其检测下限(S/N = 3)为0.008μg L-1。
